I was young. Probably 8 or 9. My family's extremely big Disney nerds and the idea of visiting all these Disney worlds to save the world was just so intriguing to me, so I begged my parents to get it for me and they did. Fell in love right away with the characters. I didn't beat KHI though, it was too difficult for me at the time. Atlantica's controls were too frustrating for me. I got KHII when that came out on release day (was very confused playing it since I didn't finish KHI OR play CoM), and I DID end up finishing that one. Then I picked up CoM for the Gameboy and beat that and EVENTUALLY beat KHI. It was a mess. I just last year played every game in order for the first time.
